Please Help: Black screen on Start up.

We lost our power due to a storm yesterday. My week old intel iMac was asleep when the power was cut and when I re-booted, all I got was the start up sound and then a black screen.
The light in the mouse is visible and when the spacebar is pressed I hear the error sound.
I have re-set the pram several times as well as left it un-plugged for and an hour. No change.
Any ideas?

Insert your installation disk, restart your Mac while holding the 'C' key down. It will take a little longer, but once booted up, choose File>Utilities>Disk Utility and Repair the Disk. Then restart as normal and see if that helps. You may need something more robust from a 3rd party, like DiskWarrior (which I think should be owned by all Mac users personally), to perform a proper repair. But anyway, try this and post back.

Please help - black screen blinking cursor 24" imac and XP home sp2

Brand new 24" imac purchased yesterday from the apple store with a 4 gig ram upgrade (i.e. all the newest stuff/versions). All updates installed & current.
Brand new (clean & scratchless) copy of Windows XP Home with SP2.
I ran the bootcamp assistant and made a 20 gig windows parition (so its under the 32 gig limit of fat32).
Following the installation procedure the windows disk is inserted, the machine reboots and then it just sits there with a black screen and a blinking cursor. The CD drive stops spinning and no progress from that point forward.
I then read on here some had better lucky with a "copy" of the original windows disk so I duplicated it in this Mac (i.e. burned with its own drive) but exactly the same problem with the burned copy (which also opens fine from within OSX).
I'm at a loss... where to go from here? We decided to try apple because they assured us we could run our "windows only aps" on the bootcamp side of the hardware but bootcamp isn't working!
Please advise...
If any of this helps:
OS X Version 10.5.2
2.8 Ghz Intel Core 2 Duo
4 GB 667 Mhz DDR2 SDRAM
Model name: iMac
Model id: iMac8,1
Boot Rom Version: IM81.00C1.B00
SMC Version: 1.30f1

Welcome to the Apple forums:
Be sure your XP disk had SP2 embedded into XP, and not a separate file or patch.
Also be sure your disk is not an ISO image but a real disk, with files on it. You can look at them using your Mac. Insert the CD or DVD and doubleclick the disk icon.
You should see most or all of the following files and folders:
(HOMEWITHSP2)
AUTORUN.INF
DOCS
DOTNETFX
I386
README.HTM
SETUP.EXE
SETUPXP.HTM
SUPPORT
VALUEADD
WIN51
WIN51IC
WIN51IC.SP2
When you copied the disk, did you make sure your copy was Windows readable? Mac has several formats, one of which is Mac-only for data CDs. You need to select the universal mode, Mac and Windows for the data image and when burning the image.
Also be sure you selected to close or finalize the CD after burning or it cannot be read by Windows.

Please help. black screen when copying back to tape

I would be very grateful of any help. I am trying to copy a movie back to tape however when i do so it results in the recording on the tape being completly black. it has gone through the process but just left a black screen.
very desperate.
Thanks

... and it did work before...? not all European camcorders allow a DV-IN...
cable checked?
finally: iM handle both video standards, even allows to import PAL footage into a NTSC project.. but cameras are 'hardwired' to one standard.. make sure, your project has same standard as camera.. (besides: Apple lingo is a little 'cryptical': '25 frames per second' = PAL, '30fps' = NTSC)
it could have happen, that you incidently created a NTSC project with your PAL footage. and now, it is impossible to playout THAT into/onto (english??) tape ...

Got black screen on start up of iMac help

Help

Hi, see if this can be done...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Macbook pro-Freezes with black screen at start up.

Macbook pro-Freezes with black screen at start up. I've tried inserting the Mac OS X install disc to run the hardware test(Restart and hold down D), But it still does nothing. Just the black screen. Now I can't get the disc out. I've tried holding down the track pad key upon start up but that doesn't work neither.
What do I do??? Please help.

Remove the battery to find your serial number in the battery bay. Then you can look your MBP up on EveryMac.com:
http://www.everymac.com/ultimate-mac-lookup/
That will give you all the information on your Mac.
This is assuming that you have the MBP with the removable battery and not the unibody. The unibody has different graphic chips.
Good luck!

BLACK SCREEN on start up with 3 beeps, FREEZES when power unplugged, IF IT BOOTS splash screen freezes, OVERHEATING REQUIRED TO BOOT - 0x7B, Event 41 kernel-power

Issue: One day I unplug the power, the screen freezes and I get frozen music sound. I shut down, start up, I get 3 beeps (1 short 2 long), which indicates a Video failure according to the Thinkpad Laptop beep code list.
How I solve the issue day-to-day: I turn the heat up - I disconnect the battery and hard drive and plug in the power then turn it on. I will wait until the underneath is searing hot with a blanket blocking the fan's flow of air, I mean way hot because any
cooler and it won't start. Plug stuff back in, Hard drive first, Battery second, turn off with power button hold, unplug power, replug power.
I turn it on, no beeps, it goes past the first Lenovo screen, then gives me a prompt because it "didn't shut down properly" and continue regular startup. What happens next is the Windows logo appears,
and just as the animated windows logo starts to move (you see 2 small colored dots on the screen), it freezes. I see this every time, I know naturally that it means that the laptop is still too hot to go past that point, so I shut it down and try again. After
about 5 - 10 tries it will go past the splash screen and into the login area, then it's all fine.
Sometimes when I unplug the power from the back by accident it will freeze. By accident I mean that the connector wiggles it's self out easily. This unplug freezing thing started happening about 1 week before the 3 beep black screen problem started rolling,
so I'm putting 2 together.
Errors:
I got a Blue Screen of Death the first time I started it up with the overheating ritual, but I never got it since. It was 0X7B.
I got another Blue Screen of Death about a week ago, but came as it was on already and I had been using it, and said something about disabling Cache or Shadowing in BIOS. I never got it since.
Event Viewer events found:
1. Kernel-Power, Summary page.
There are critical events for a few things like Kernel-Power, Event ID 41, Task Category (63). There are 19 of them, each day 1 or 2 of them but mostly 1, so this maybe corresponds to my daily ritual.
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
2. Kernel-Processor-Power - Event ID 37, task category (7)
"The speed of processor 1 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report."
3. LMS - HCMI - Event ID 2, Task Category: none
"LMS Service cannot connect to HECI driver".
I came across a very sluggish performing control panel for Nvidia before and after this problem, and I tried installing a newer version, which I had to jump through a few hoops to do, like uninstalling first, not just updating. At first it said that the
driver wasnt for the system, which was wrong. I made it work somehow, but it was still sluggish. I rolled it back to an earlier driver, and now it works fine. No sluggish performance / slight freeze window thing going on.
MSCONFIG.exe, Boot Advanced Options: I have tried twice to change this 1 setting, check box "Number of processors" and change to 2 processors, because I do have 2 processors. I have been able to change
this in the past, but it does not save the setting now, and I believe this option was selected before I started having problems, and settings did not disappear then.
What could this be. The small round BIOS battery? The video card like everyone presumes? (I.E. the entire motherboard replacement), Software? The wiggly power input area? (Not enough power getting in?), Firmware of some sort? The BIOS software being wrong?

Please excuse the small text at the beginning, there isn't an option to un-do that error.

You are very wrong about that mystified. What do YOU think made my computer work without beeping at all hu? (I bet you're gonna tell me). I figured it out.
RE-INSTALL WINDOWS 7 OS.
SOLVED.
DOESN'T BEEP ANY MORE.

NB 305 black screen on start up

My NB305N410BL displays a black screen on start up. It had worked fine the prior night. You can hear the "beeps" for the start page but no mouse or image ever. Any ideas on the problem? Thanks, Karen

Try this, disconnect the battery and charger. Hold the power button for 15 seconds and reconnect everything and turn on the computer...hopefully this helps you fix the issue...

I solve my problem of black screen when starting up my Mac pro, namely by the button lighting and then i saw the login screen. Hopefully it works for you too.

Lightroom 5 book module - suddenly the book 236 page book that I have been working on has mysteriously disappeared!!! Please help, as I am starting to panick!!!

I have been working hard on making a book in the Lightroom 5 book module for the past 6 months. I am close to being finished, and am doing my final edits. Suddenly, my book is only appearing as a 2 page blank book under the same heading, and has no images showing. When I go to the library, or develope module all the photos are still there, but under book module they are suddenly gone. Please help, as I am starting to panick!

First, are you 100% certain? In Library, double click the book. Does this take you to the "2 page blank book"? I assume yes, but let's be certain.
What version of Lightroom? 5.7 is the latest.
Restore a copy of your catalogue from a recent backup. Go to the book collection in Library, right click it, and choose Export as Catalog. This should create a small catalogue containing your book. Open it, and check it's right - if not, try an earlier backup.
If it's OK, then return to your main catalogue, rename the "2 page blank book" by putting "old" on the end, and use File > Import from Another Catalogue to bring the small catalogue into it. Does this solve the problem?

Presario f700 black screen at start up,

presario f700 black screen at start up, if left to own it flashes hard drive light once fan starts then turns off the starts again can get it to stop this sequence by pressing certain keys but screen always stays black and remote screen does not turn on. Have tried removing memory, hard reset, removed ram, have tested hard drive out of device. Anything else I can try.
Book says 15secs for a hard reset, one post said 30secs, which is correct

Hi, 30 secs is the better of the two options there. I am assuming the Hard drive tested fine? You can try turning the computer on with out the hard drive in it and see if you atleast get some text saying not bootable device or if you are able to boot into BIOS. If this does not happen you can switch out the ram chips. (boot with one chip then take it out and boot with the other) see if these work. If these steps fail its more than likly more of a hardware issue with the systemboard.
While I may work for HP, my posts and replies are my own and should not be mistaken for statments made by HP as a whole.

My Mac Pro is acting up.
If I do a reset after its beenruning for a period of time I get a black screen at start up. I have tried multiple different monitor cables and nothing seems to work. It does seem to resart and I can here the start up chime but no display. If I unplug the machine and let cool for 1/2 ~ 1 hour it then turns back on with no problem.

Any ideas? Bad graphics card?

AC if you used it this once would pay for itself. Same for a good solid UPS - a good one can stop that 1/100,000 surge that takes out a modem (if you filter of course).
I've known people that never knew you could filter coax cable or dsl and we get enough severe storms it has been, not if it happens, but when.
Unlike the X1900 which had a air chamber and would cause clogging you really should not need to and be pulling it out to clean dust all that much if at all.
People have gone through 2 or 3 ATI 5770s and some 5870s due to what are probably design or bad batches especially the first months run.

Please Help: Black screen on Start up.
